提出了一种用于直升机/涡轴发动机综合控制的变旋翼转速串行优化方案.首先基于Levenberg-Marquarat(L-M)算法/一维最优搜索算法,在保证直升机飞行状态不变的情况下,寻优得到旋翼所需最小功率,再通过优化发动机操纵量,在保证发动机约束成立的条件下得到当前发动机运行最优工作点,即达到直升机巡航时油耗最小或者涡轮前温度最低.最后,在UH-60直升机/涡轴发动机综合控制仿真平台上进行了最小油耗控制模式的仿真,数字仿真结果表明了该串行优化方案的可行性.
A serial variable speed control scheme of variable rotor speed for helicopter / turbine engine integrated control is proposed.Firstly, based on Levenberg-Marquarat (LM) algorithm and one-dimensional optimal search algorithm, under the condition of keeping the helicopter flight status unchanged, Optimum get the minimum power required by the rotor, and then optimize the engine control volume, under the condition of ensuring the engine constraints established by the current engine optimal operating point, that is to achieve helicopter cruise minimum fuel consumption or turbine minimum temperature.Finally, in the UH -60 helicopter / turboshaft engine integrated control simulation platform on the minimum fuel consumption control mode simulation, numerical simulation results show the feasibility of the serial optimization program.
